Thing is not everyone has a ranch with just one level. I have a basement, a ground floor, and a third floor. So I tried drawing all 3 floors side by side and then I wanted to just zoom so one was visible at a time. I could drag left or right to see the other.

In either case the full screen zoom left everything worthless to see.

Tabs for different floors of a home could be a great way to handle this while retaining readable zoom levels. I have a split-level home, which gives it twice as many floors as other typical home layouts.

I think for the UI3 the possible changes to be done are limited to graphics and functionality but, conceptually speaking, it will remain the same. This is the reason we've started the UI4 in order to find a better solution for the floor planner, in which all the infos to be readable and the access to different sections to be fast and easy.

I can say that we have a nice concept that will be presented on the UI4 Proposals topic. Waiting everybody there to share opinions. We are saying that the new interface will not need any more zoom or pan in order to see all the rooms and devices. @guessed, does it sound good? :-)
